Abstract
A dispensing mechanism is adapted to eject a test sensor from a cartridge opening formed in a cartridge containing test sensors. The dispensing mechanism comprises a gear rack, a gear, and a wheel. The gear rack includes a first portion and a second portion located generally parallel to one another. The second portion of the gear rack includes a first plurality of teeth. The gear includes a second plurality of teeth that are adapted to be engaged by the first plurality of teeth upon movement of the gear rack. The wheel is operatively engaged by the gear and is adapted to dispense the test sensor from the cartridge opening and to seal the cartridge opening. The movement of the gear rack in a first direction causes the gear to rotate causing the wheel to rotate. The rotation of the wheel dispenses the test sensor through the cartridge opening.
